I don't understand why i'm being downvoted or why there's anything wrong with analytical speculation of this type, even about a tragedy. If anything, this very site and its comments are loaded with exactly that kind of commentary, done mostly in good spirit and tolerance for those who do it. No, i'm not an explosives expert or professional with detailed knowledge of blast yields, but like many of you, I have something of a strong curiosity in a topic irrelevant to my professional occupation. So, based on educated guesstimating, I decided to share a polite opinion about it, like so many others regularly do on HN. Chill.
